Abstract

A head rest for a car seat used to transport a child in an automobile is positionally adjustable vertically along the seat back on which the head rest is mounted. A latching mechanism, actuated by a button at the top of the head rest, is located within the frame of the head rest and includes a releasable latch engagable with the channels slidably supporting the support rails of the head rest. A
retainer clip is mounted at the top of the channels to prevent the head rest from being separated from the seat back once assembled thereon. The head rest includes a pair of laterally spaced wings that are pivotally connected to the rear support portion of the head rest to be positionally adjustable relative to the child's head through an angular displacement of approximately 45 degrees. The pivot mechanism is operable to lock the wings in the selected position.

Claims (17)

1. A head rest for a car seat utilized for transporting a child in an automobile, said head rest being mountable on a seat back, comprising:

a frame including a support rail engagable with a corresponding hollow channel in said seat back to permit said frame to move vertically relative to said seat back;

a rear support portion mounted on said frame;

a pair of laterally spaced side wings pivotally connected to said rear support portion by a pivot mechanism so that said side wings are independently angularly positionable relative to said rear support portion irrespective of the vertical position of said frame relative to said seat back; and a latching mechanism operable to engage said channel to secure said frame in a selected vertical position.
2. The head rest of Claim 1 wherein said pivot mechanism includes a locking apparatus operable to lock said side wings in a desired angular position.
3. The head rest of Claim 2 wherein said pivot mechanism comprises:

a first mounting member connected to said rear support portion;

a second mounting member connected to the corresponding said side wing and being rotatably connected to said first mounting member;

said locking apparatus being positioned between said first and second mounting members to control the rotational movement of said second mounting member relative to said first mounting member; and an actuator operably connected to said locking apparatus for selectively allowing a release of said locking apparatus from said first mounting member.
4. The head rest of Claim 3 wherein said locking apparatus comprises:

a gear mounted for rotation with said second mounting member; and a spring biasing said gear into engagement with both said first and second mounting members, said actuator being operable to move said gear axially against said biasing force out of engagement with said first mounting member, thus allowing said second mounting member to rotate relative to said first mounting member.
5. The head rest of any one of Claims 1 to 4 wherein said channel is provided with a retaining clip to retain said support rail within said channel and prevent said head rest from being removed from said seat back.
6. The head rest of Claim 5 wherein said retainer clip comprises:
a base member affixed to said seat back;

a retainer catch slidably mounted within said base member; and a spring to bias said retainer catch outwardly from said base member.
7. The head rest of Claim 6 wherein said latching mechanism is detachably connected to said support, rail and includes a latch keeper that projects outwardly therefrom into engagement with a corresponding opening in said channel to secure said head rest in a selected vertical position, said retainer catch having a sloped upper surface to allow said latch keeper to cam said retainer catch into said base member against said biasing force.
8. The head rest of Claim 7 wherein an upper portion of said channel is widened to accommodate the receipt of the corresponding said support rail with said latch keeper protruding therefrom until positioned below said retainer clip.
9. The head rest of Claim 8 wherein said latching member defines a ledge against which said retainer catch interferes to prevent said support rail from disengaging the corresponding said channel.
10. The head rest of any one of Claims 1 to 9 wherein said latching mechanism comprises:

an actuator supported on said frame for movement between a home position and a release position;

a cam member engaged with said actuator and being spring-loaded toward said home position;

a drive member located in said support rail;

a flexible link interconnecting said cam member and said drive member;

a latch member positioned for engagement with said drive member and being engagable with said channel when forced outwardly from said support rail into engagement with said channel.
11. The head rest of Claim 10 wherein said latch member is a resilient member oriented to be housed within said support rail until driven outwardly into engagement with said channel, said latch member including a latch keeper that engages said channel.
12. The head rest of Claim 11 wherein said drive member drops below said latch member when said actuator is moved into said release position moving said cam members and said drive members through said flexible links, whereby said latch member is free to retract into said support rail to disengage said latch keeper from said channel.
13. A car seat for transporting a child in an automobile, comprising:
a seat member;

a seat back connected to said seat member, said seat back including at least one hollow channel;

a head rest including at least one support rail in register with the corresponding said hollow channel to be received therein when said head rest is mounted on said seat back such that said head rest is vertically positionable relative to said seat back;

a retainer clip mounted on said seat back and being operable to prevent said at least one support rail from disengaging the corresponding said hollow channel, said retainer clip including a base member affixed to said seat back, a retainer catch slidably mounted within said base member, and a spring to bias said retainer catch outwardly from said base member; and a latching mechanism including a latch keeper that projects outwardly from said at least one support rail into engagement with a corresponding opening in the corresponding said channel to secure said head rest in a selected vertical position, said retainer catch having a sloped upper surface to allow said latch keeper to cam said retainer catch into said base member against said biasing force.
14. The car seat of Claim 13 wherein an upper portion of said at least one channel is widened to accommodate the receipt of the corresponding said support rail with said latch keeper protruding therefrom until positioned below said retainer clip, said retainer catch interfering with a ledge operably associated with said support rail to prevent said support rail from disengaging the corresponding said channel.
15. The car seat of Claim 14 wherein said head rest includes a rear support portion and a pair of laterally spaced side wings pivotally connected to said support portion by respective pivot mechanisms to permit an angular positioning of each said side wing relative to said rear support portion.
16. The car seat of Claim 15 wherein each said pivot mechanism comprises:

a first mounting member connected to said rear support portion;

a second mounting member connected to the corresponding said side wing and being rotatably connected to said first mounting member;

a locking apparatus positioned between said first and second mounting members to control the rotational movement of said second mounting member relative to said first mounting member; and an actuator operably connected to said locking apparatus for selectively allowing a release of said locking apparatus from said first mounting member.
17. The car seat of Claim 16 wherein said locking apparatus comprises:

a gear mounted for rotation with said second mounting member; and a spring biasing said gear into engagement with both said first and second mounting members, said actuator being operable to move said gear axially against said biasing force out of engagement with said first mounting member, thus allowing said second mounting member to rotate relative to said first mounting member.
